Answer the questions, take the photos, and the AI writes the report. When it’s done, you’ll see how many things it found. The full report is £9.99 ex VAT, against £75 to £150 for a firm’s visit.
Walk the property and answer what you can see. DwellFlow applies the temperatures and checks from HSE guidance as you go, and reads the whole survey back before you finish.
HSE says most landlords can assess the risk themselves. What’s new is the tool for doing it properly.
If your letting agent has just written to you about Legionella, this is the duty they meant. Under the Health and Safety at Work etc. Act 1974 and COSHH, whoever is responsible for a rented property must assess and control the risk from Legionella — for a managed property that is usually the landlord, unless the management contract puts safety in the agent's hands. HSE is clear that most landlords can assess the risk themselves — and equally clear that the assessment has to be a real one. A tick sheet with no readings and no evidence records nothing about the property it claims to assess.
No assessor visit to schedule, no waiting for a contractor's diary. The person already going to the property does the survey.
A guided survey that asks about what is actually there — room by room, fitting by fitting. Allow thirty minutes to an hour, depending on the size and type of the water system — and quicker once you have done one. It works with no signal, so a loft or a stone-walled terrace loses nothing. No prior water hygiene knowledge needed — nobody is asked to judge anything, only to look, measure and photograph.
One thing you must have: a thermometer with a probe — a digital cooking one counts, or about £20 from any tool merchant, in stock today. Not an infrared thermometer: those read the tap rather than the water. Then, only if the property has them: a tape measure for a water tank or cylinder, and a torch for a loft.
Rules built from HSG274 and ACoP L8 turn the answers into findings, priorities and a risk rating. An AI completeness check queries anything that does not hang together while the surveyor is still in the house.
The assessment, a sheet for the tenant and a written scheme of control — issued the moment the survey is submitted, with a schematic of the water system drawn from what was recorded. No diary, no waiting on anyone.
Almost every product in this market stops at the assessment. ACoP L8 asks for an assessment of the risk and a written scheme for controlling it.
Every reading, every asset, photographed evidence, priority-rated recommendations with the clause behind each, a risk score to BS 8580-1 and a review date.
Written for the person living there: the temperatures measured in their home, what the numbers mean, and the handful of habits that keep the risk low. One page for a simple property.
The ongoing routine, built around visits that already happen — the annual service, tenancy changes — plus what to do when a property stands empty and when to have the assessment reviewed.
Then it keeps working. Each recommendation carries a date: record it as done — or not done, and why — against the property, and DwellFlow emails a reminder a week before each date and the day after it passes.
Letting agents and portfolio landlords: import the managed book from a spreadsheet, assign each property to the staff already visiting it, and every finished survey files its three documents against the property they belong to. Housing associations and councils, where the people already attending — the gas safety visit, the void inspection — can carry this with them, and the four-thousandth report holds to the same standard as the first. A landlord with one or two properties, who can do the whole thing on a phone this afternoon — no staff, no assessor, no waiting. And the contractor already at the door for the gas safety check or the EPC, who can carry this with them, survey while they are there, and offer it to every landlord they work for. And the owner of a holiday let or a serviced apartment — a domestic property let in the course of a business, so the same duty applies, and one that stands empty between guests, which is exactly what an assessment looks for.
Because nobody drives anywhere. Every property is £9.99 ex VAT, however many you buy. Pay by card and your account is ready the moment you pay. Above a hundred, tell us the size of the book and we reply the same working day. Either way there is a full example assessment to read before you commit to anything.
